Comet Debris Causes Significant Navigation Issues During Rosetta’s Latest Close Flyby

This stunning scene was created from two NAVCAM frames acquired at 19.9 km from the comet centre on 28 March. The scale is about 1.7 m/pixel and the image measures 3.1 x 1.7 km. The image has been adjusted for intensity and contrast, and the vignetting has been fixed. Credits: ESA/Rosetta/NAVCAM – CC BY-SA […]

Curiosity Discovers Biochemically Accessible Nitrogen, Key Ingredient Needed for Martian Life

Curiosity detected biochemically accessible nitrogen here at John Klein drill site! Curiosity accomplished historic first drilling into Martian rock at John Klein outcrop on Feb 8, 2013 (Sol 182), and discovered a habitable zone, shown in this context mosaic view of the Yellowknife Bay basin taken on Jan. 26 (Sol 169). The robotic arm […]

Opportunity Arrives at Alien Gateway to Clay Minerals at Spirit of St. Louis Crater
